I've eaten gluten-free in major cities around the world. Blossom's desserts, biscuits, and croissants (all made in an entirely gf environment) are amazing--among the best gluten-free goodies I have found. Rochester is lucky to have her.
She is a one-woman show with a lot of private cake orders, so she does have limited hours. I'd recommend checking out The Gluten-Free Chef's FB page for when she is open.

One of the best gluten free places in rochester. Its right around the area of some main restaurants in the area. If you're still hungry after brunch, lunch or dinner come here to get your gluten-free dessert! Decently priced, fresh and a dairy free & vegan option.
